OHIMNEY CONNECTOR Arthur H. Klein, Milwaukee, Wis. Application May 21, 1937, serial No. 149,917

l5 Claims. (Cl. 12S- 314) y Thisl invention relates to furnaces and boilers 'and more particularly to a. connector between a furnacey or boiler smoke pipe and a. chimney.

I'he usually accepted method of vmaking lthe '5 connection between a smoke pipe and a chimney tate cutting oif the bolts with a cold` chisel in order to clean or repair the flue.

One object of the present invention is to provide a smoke pipe connector which will hold the smoke pipe rmly in place in the chimney without the use of bolts.

Another object of the invention is to provide 25 awsmoke pipe connector which will simplify the process of taking apart and assembling the smoke vpipe vwith the chimney.

further object is to provide a connector between a smoke pipe and a chimney which will positively grip and hold the smoke pipe.

Another object is to provide a connector between a smoke pipe and a chimney which can be readily disassembled.

. Another object is to provide a connector between a smoke pipe and a chimney, including a thimble xed in the chimney and a collar surrounding the smoke pipe, in which insertion of the collar in the thimble fixes the collar in the thimble and clamps the smoke pipe in the collar simultaneously.

These and other objects, thenature of which will becomev apparent as the description of the invention progresses, are accomplished by means ofthe preferred form of the invention shown on the accompanying drawing and described in the following specification, andsuch modifications thereof as may fall within the scope of the appeided claims.

In'the drawing: 1

. 50 Fig. 1 is a cross-section through the center of Inthe drawing, in which like numerals indicate like parts in both views, a thimble 5 is shown grouted into the Abase of a chimney 6. The thimble is preferably made square because of the ease of forming a square hole in the brickwork of the chimney, but may be other shapes if desired.

The thimble 5 has one or more wedge surfaces 'l on the interior of each side of the thimble. The wedge surfaces or Wedges 1 engage cooperating Wedge surfaces or wedges 8 on a collar 9 to force the collar 9 into engagement with a smoke pipe I and simultaneously wedge the collar 9 in the thimble 5.

'I'he collar 9 is made in two identical halves and comprises a cover plate Il with a central hole l2 therein to receive the smoke pipe in, and a skirt I3 which surrounds the exterior of the hole I2 and supports the wedges 8. One half the hole I2 is formed in each half of the collar 9 so that the collar can be put in place around the smoke pipe l0 after the smoke pipe has been inserted in the thimble 5.

The cover plate Il is of sufiicient size to form a complete cover for the thimble 5 and prevent the escape of smoke from the chimney or any excess air filtering in between the cover Il and the thimble 5.

By making the collar 9 in two halves, the wedges 1 and 8 force the halves into engagement with the pipe I0 and form a tight joint between the pipe and the collar and simultaneously fix the collar in the thimble 5. A further advantage accruing from the use of the split collar is the ease with which the smoke pipe can be adjusted and assembled in the connector.

In use, the smoke pipe I0 is adjusted on the furnace (not shown) with the free outer end inserted through the thimble 5. One half of the collar 9 is then placed about the pipe I0 and forced into place in the thimble. The other half of the vcollar 9 is then placed on the pipe I 0 and the collar inserted into the thimble 5. As the second half of the collar is put in place in the thimble, the wedges on both sides of the thimble cooperate with corresponding wedges on the collar to clamp the pipe in the collar. At the same time the wedges grip the collar and hold it securely in the thimble without the use of bolts and nuts or other fastening means.

Having thus described the invention, it is apparent that it is susceptible to various changes and modifications. It is not, therefore, desired to limit the invention to the precise form herein shown and described but only by the scope of the appended claims.

pieces of the collar into gripping engagement with the smoke pipe.

2. A smoke pipe connector adapted to connect a smoke pipe to a chimney, comprising, a thimble secured in the chimney, a wedge surface formed Within said thimble, a collar adapted to surround the smoke pipe and to fit withinthe thimble, and a Wedge member formed om said collar and adapted to engage with said first' named Wedge member to secure vthe thinrble" and collar in assembled relationship.

3. A smoke pipe connector adapted to connect a smoke pipe to a'chimney, comprising, a thimble secured in theY chimney a' wedge surface@ formed on the: interior of sai-d, thimole, ar collar formed ofY two parts having` anl open-ing to receive the smoke pipe a portion of said. collar. adapted to t within the thimble, and ai wedgey surface formed on one part of said collar adapted to cooperate With the rst named wedge surface to simultaneously secure the collar in the thimble and clamp the smokel pipe in the collar.

4. A smoke pipe .connector ofthe character described` comprising,Y aY thimble adapted to` be secured in an opening ina chimney,'a plurality of wedges formed on the interior of said thimble, a collar having an opening therein adapted to receive a smoke pipe, and a plurality of wedges carried by said collar surrounding said opening and adapted to cooperate with the wedges on the thimble to hold the thimble and collar in assembled relationship.

5. A- smoke pipe connector of the character described. comprising, a thimble adapted to be secured in an opening in a chimney, a plurality of wedges formed on the interior of said thimble, a collar. having a hole therein adapted to receive a smoke pipe,r a skirt surrounding said hole, and ai plurality of wedges carried by said skirtfadapted to' engage the Wedges. on the. thimble to simultaneouslyl secure the smoke pipe in the collar and the collar in the thimble; I
